Definitions

  • the MSC 300 starts out similarly to FIG. 2 in triggering a manual CSG search request, conducting the search, and reporting the results 310 - 316 , however, upon receiving the Manual Search results from the Access Stratum/L 1 in 316 , the NAS stores the CSG search results, including the supported RATs, in a local database 317 .
  • This local database may be located in a memory component of the mobile terminal, e.g. a memory component of the baseband modem, SIM, etc.
  • the local database will store the Manual Search results, for later use.
  • the baseband modem is configured to, in a first selection of the CSG cell, collect the CSG information received from thee RF unit and store the CSG information in a databse; select a macrocell for connecting to a network such as the PLMN; detect the CSG cell; and trigger a switch to the CSG cell after determining that the CSG cell is the highest ranked cell on its frequency, retrieving the CSG information from the database, and performing a criteria check, which may consist of using the CSG information in order to check to see if signal strength of the CSG cell is appropriate for cell selection.
  • Example 13 the subject matter of example 12, further comprising storing the database in a memory of the communication device.
  • Example 62 the subject matter of any one of examples 55-61, wherein retrieving the CSG information from the database further comprises identifying the target CSG cell in the database by the target CSG cell identity.
